IMPRQVEMENT IN THlLL-COUPLINGS.

Specification forming part of Letters Patent No. l74,930, dated March 21, 1876; application filed August 7, 1875.

To all whom, it may concern Be it known that I, WM. W. ANDERSON, of Ihiladelphia, State of Pennsylvania, have invented an Improvement in Thill-(Joupling, of which the following is a specification The object of my invention is to make an improvement in thill'coupling to prevent rattling, and to take the place of gum that has heretofore been used, by constructing in the ordinary thill-box now gin general use a rebeen a desideratum which the gum plug has only partially and temporarily supplied, from a lack of regular elasticity, which at first is so great as to cause cutting of the thill-eye and bolt, and after a few months wear is so diminished as to cause the gum to become loose and ineffective, whereas the pressure made by the metallic or steel spring is so constant and regular as to prevent the cutting of the bolt, or scarcely any perceptible wear, even by long and continued use.

I claim as my invention A chill-coupling clip with a transverse bar, provided with a cavity, A, combined with a metallic spring, B, seated in said cavity, and bearing directly against the ordinary shaftiron, substantially as shown and described.
